保温ボトル用ふた（交換部品）

The seal clicks into place perfectly—no more leaks in my bag. Fits my insulated bottle exactly like the original, so it’s good as new. Exactly what I needed.

I've been using this as a replacement for my old bottle lid, and the threading lines up perfectly so there's no leaking. The seal seems tight, which is exactly what I needed to keep my coffee hot during morning commutes.

Finally, a way to resurrect my favorite bottle instead of tossing it. The lid fits snugly and has the same satisfying twist-click seal, so it’s holding up well after a few weeks of daily use. Slightly pricey for a spare part, but way cheaper than a whole new bottle.
